Abstract
There is described a method and an apparatus for pulse width modulation with a predefined switching period having an adjustable ratio of the switch-on duration to the switch-off duration, in which a quantized signal is converted into a pulse-width-modulated signal and is generated in the form of a discrete pulse sequence of switch-on operations and switch-off operations with the predefined switching period, the switching edge for the switch-on duration and/or the switch-off duration being determined on the basis of the ratio of the switch-on duration to the switch-off duration.
